It most definitely is. I'm an algorithmic equities trader and there are definitely super easy opportunities in the BTC market right now.

Yep. That's why I am sad this f*** API doesn't work.

Have you tried to just use the "user-friendly" api to login yet?

Mmmm sorry but I don't get it. What is the "user-friendly" api. Till now I have used the urls as indicated on the mtgox api page...

I mean, logging in by using the postbacks for when you normally log into the site?

e.g. Login here -> https://mtgox.com/users/login -> https://mtgox.com -> to buy/sell your coins.
